Influence of environmental policies on waste treatment

Abstract

[EN] Countries' growth along with the need to protect the environment has made waste management a major global concern. In this study, a detailed analysis is carried out of the current situation in 41 countries belonging to the OECD and/or the European Union, in order to identify the most sustainable practices that could be successfully implemented in other nations with similar characteristics. Cluster analysis is used to detect homogeneous groups, shedding light on the possible connection between environmental policies and waste treatment. Contingency tables are employed to determine the relationship between the effectiveness of the policies adopted and two indicators of sustainable practices: material recycling and waste generation. The study is conducted using statistical information from the Sustainable Governance Indicators project and the OECD, with data referring to 2018. Five internally homogeneous groups of countries have been identified, where Israel, Turkey and USA have the lowest participation and compliance in environmental policies. Also, the results show that countries with a high degree of participation in environmental treaties (Croatia, Denmark, Finland, France, Germany, Japan, Luxembourg, the Netherlands, Norway, Spain, Sweden, Switzerland) are making great progress, reducing the use of landfills in favour of other, more environmentally friendly options. Moreover, the contingency tables confirm that the effectiveness of policies translates into a clear trend towards recycling and, to some extent, reduces waste generation.
